15.7 The very busy C-c C-c key

The key C-c C-c has many purposes in Org, which are all
mentioned scattered throughout this manual. One specific function of
this key is to add tags to a headline (see Tags). In many
other circumstances it means something like “Hey Org, look
here and update according to what you see here”. Here is a summary of
what this means in different contexts.

- If there are highlights in the buffer from the creation of a sparse
tree, or from clock display, remove these highlights.

- If the cursor is in one of the special #+KEYWORD lines, this
triggers scanning the buffer for these lines and updating the
information.

- If the cursor is inside a table, realign the table. This command
works even if the automatic table editor has been turned off.

- If the cursor is on a #+TBLFM line, re-apply the formulas to
the entire table.

- If the current buffer is a capture buffer, close the note and file it.
With a prefix argument, file it, without further interaction, to the
default location.

- If the cursor is on a <<<target>>>, update radio targets and
corresponding links in this buffer.

- If the cursor is in a property line or at the start or end of a property
drawer, offer property commands.

- If the cursor is at a footnote reference, go to the corresponding
definition, and vice versa.

- If the cursor is on a statistics cookie, update it.

- If the cursor is in a plain list item with a checkbox, toggle the status
of the checkbox.

- If the cursor is on a numbered item in a plain list, renumber the
ordered list.

- If the cursor is on the #+BEGIN line of a dynamic block, the
block is updated.
